How do we educate ourselves for democracy?

How [is] a democracy to become so well-educated [that it can] find the answers to [its] problems? The necessary education for popular government cannot be obtained in the schools and colleges, from books, newspapers, lectures, and the radio, alone. Popular education is indispensable, and I should be the last to decry it. But it is insufficient.
The kind of self-education which a self-governing people must obtain can be had only through its daily experiences. In other words, a democracy must have a way of life which educates the people for the democratic way of life. [...] If the people do rule, they must rule in a particular way.

-- Walter Lippmann, The Good Society, 1937
